found the dyno graph of the gt-rs status?

so judging by the graph with the 3 turbo setups compared, the 3071r doesn't appear to be that much laggier then the smaller t518z correct? if i read correct then the gt3071r comes on roughly 500rpm later, and with less torque earlier aswell? Also i thought the t518z is only becomes efficient or to its full potential when you start pushing ~20psi+, would that effect the lag but push power outputs closer to the 250kw mark? i know all this depends on supporting mods but just asking as an idicator. Also status, you wouldn't be able to have a std sr20 with a gtrs / 2871r 52t would you?. to compare it with the t518z with power and torque, as i heard the t518z makes more torque and spools earlier then a gtrs? but the gtrs being BB? From your graphs, im starting to lean to the t518z, because i like the bulk amounts of torque early, but then again i question if i opted the 3071r route, with earlier cams? (256's) would that bring on boost and torque earlier?

well mainly aiming for roughly 250-270kw, but dont want to be pushing to much or leaning out, as i will onli be using bp98... im still stuck on the t518z?.. as a few people have gotten decent numbers about the 250kw mark... but then, if you say the 3037 .73 a/r is not much difference in lag factor, but has the option to push more power, .then that turbo could be the possibly pick. as mentioned, only want around ~350hp... street car, but occasional track days... also, what cams would you recommend to make the most of ; a) t518z (8cm or 10cm)... b) 3037s 0.73... is there any benefit in mix and matchin cams, (ie. 256/64 or 264/272) ... and how much lift is beneficial to the goal i am aiming? only want a fairly responsive turbo with a boot til redline, as current setup with power fc, t28bb, fmic, pod, fuel pump, exhaust - doesnt lose by much to a few sr's running gt3071r's 0.64 and 0.86s doing 330+? ... which i find weird?

interesting read disco.. was originally planning to go the hks 3037 route, but always thought lag mite be an issue? and from reading alot of good results with people using the t518z making ~260kw mark while keeping good response. So in that case, i gather your preference would be the hks 3037 0.73 a/r? i also thought, that the t2 flange would become restrictive when chasing big numbers? or do t2's with 0.73 and SR's make a realy good combo?

and to add status, can you add a graph of the 3071r against the 8 and 10cm ... champion x2!

cheers status! much appreciated... also list what supporting mods on each etc.. plans are fresh s15blacktop, 740's, z32, power fc, and either the 8 or 10cm t518z

just wondering, how much difference would there be between the 8cm and 10cm versions?.. referring to spool and output differences -- so the t518z has a t25 footprint?... do they come out in any t3 flanges?

its a gtst with a rb25 with 26 bottom end,crank,pistons and rods..
